boot takes too long (swap?)

[Bruno Schneider <boschneider@gmail.com>]

I have a notebook with Debian testing (Stretch) that suddenly started
going through long (4 min) boots.

Something disk intensive stops the boot process for more than 3 miinutes.

Looking at dmesg, I see a large time gap here:

[   20.661252] Adding 4208992k swap on /dev/sda1.  Priority:-1
extents:1 across:4208992k FS
[  196.805214] EXT4-fs (sda4): mounting ext3 file system using the
ext4 subsystem

So, it looks like swap is taking a long to mount. I checked my fstab,
and the swap line is:

UUID=d30ec1b1-0dab-455d-a7b1-51ca86631bc2 none            swap    sw
           0       0

The UUID is correct. The swap partition is working after boot.

Can anyone help on how to investigate further?
